Method Detail

createCompatibleDestImage

public BufferedImage createCompatibleDestImage(BufferedImage src,
                                               ColorModel dstCM)

Specified by:

createCompatibleDestImage in interface BufferedImageOp

getBounds2D

public Rectangle2D getBounds2D(BufferedImage src)

Specified by:

getBounds2D in interface BufferedImageOp

getPoint2D

public Point2D getPoint2D(Point2D srcPt,
                          Point2D dstPt)

Specified by:

getPoint2D in interface BufferedImageOp

getRenderingHints

public RenderingHints getRenderingHints()

Specified by:

getRGB

public int[] getRGB(BufferedImage image,
                    int x,
                    int y,
                    int width,
                    int height,
                    int[] pixels)

A convenience method for getting ARGB pixels from an image. This tries to avoid the performance penalty of BufferedImage.getRGB unmanaging the image.

Parameters:

image - a BufferedImage object

x - the left edge of the pixel block

y - the right edge of the pixel block

width - the width of the pixel array

height - the height of the pixel array

pixels - the array to hold the returned pixels. May be null.

Returns:

the pixels

setRGB

public void setRGB(BufferedImage image,
                   int x,
                   int y,
                   int width,
                   int height,
                   int[] pixels)

A convenience method for setting ARGB pixels in an image. This tries to avoid the performance penalty of BufferedImage.setRGB unmanaging the image.

Parameters:

image - a BufferedImage object

x - the left edge of the pixel block

y - the right edge of the pixel block

width - the width of the pixel array

height - the height of the pixel array

pixels - the array of pixels to set
